Instruction Manual


Preface

The WatchBP Office Central has been validated against simultaneous recorded intra-arterial blood pressure measurement, which is the

gold standard for validation of central blood pressure measurement, and showed extreme high accuracy in measuring central systolic,

central diastolic and central pulse pressure 1. The WatchBP central has passed the validation protocol of the BHS for accuracy in blood

pressure measurement (A/A) and is equipped with other innovative screening tools such as:

• An implemented atrial fibrillation (Afib) detection system that has proven excellent accuracy 2, 3 and is officially recommendation by

the National Institute of Clinical health and Excellence (NICE) in the UK 4.

• Two arm cuffs that allow simultaneous blood pressure measurement of both arms for accurate determination of inter-arm BP

differences 5, 6. This mode is highly supported by the latest ESH guidelines (2013) stating that Inter-arm difference in blood pressure is

only meaningful when obtained from simultaneous arm blood pressure measurement 7.

• Ankle-brachial index (ABI) performance that is validated against Doppler for accuracy with positive results and additionally showed

that the assessment led to a significant time reduction as compared to Doppler 8. Finally, the automated calculation of the ABI value

guarantees uniformity and prevents errors due to registration and calculation failures 9.1. Cheng, H.M., et al., Measurement Accuracy of a Stand-Alone Oscillometric Central Blood Pressure Monitor: A Validation Report for Microlife WatchBP Office Central. Am J Hypertens.

Three operation modes (cont.)

Simultaneous dual-arm measurements

In «SCREEN» Mode, the WatchBP Office Central device measures the patient’s blood pressure on both arms simultaneously, for determining the arm with the highest blood pressure value and revealing the possible presence of peripheral arterial disease.

«SCREEN» ModeSelect «SCREEN» Mode to complete fully-automated triple measurements on both arms according to recommended ESH/AHA blood pressure measurement protocols for a patient’s first office visit.


EN15


Automated triple measurements

In «SCREEN» Mode, the WatchBP Office Central device automatically takes three consecutive measurements on both arms at fixed one minute* intervals. The results of these three measurements are then averaged to conclude the blood pressure measurement.

* The measuring intervals are fixed at one minute in SCREEN mode. The interval time can be shortened by pressing the on/off button during the countdown period.

* The arm with the higher blood pressure value should be taken for ABI measurement or future blood pressure measurements.

Determine the proper arm and inter-arm difference

If the difference of blood pressure readings between two arms is more than 20mmHg for Systolic or 10mmHg for Diastolic at all three measurements, the device indicates the arm with the higher blood pressure value by displaying L or R and the “IAD” icon. The “IAD” icon and readings of the higher arm flash to indicate that more attention is needed as this patient might have peripheral arterial disease. .

WatchBP Office CentralSpecial Functions

Central blood pressure

Central blood pressure is the pressure in the ascending aorta, the largest artery that originates from the left ventricular of the heart and from where oxygen is distributed to all parts of the body through the systemic circulation.

How is central blood pressure measured?

The WatchBP Office Central uses brachial pulse volume plethysmography (PVP) waveforms 1 to determine central blood pressure. The WatchBP Office Central is designed to perform PVP at a cuff pressure of 60 mmHg. Based on the analysis of PVP waveforms the central systolic blood pressure value and the central pulse pressure value are then determined 1.

Accuracy of the WatchBP Office Central

The accuracy of central blood pressure measurement performed with an automated oscillometric device can only reliably be determined against intra-arterial blood pressure measurement. The WatchBP Office Central has been validated against simultaneous recorded intra-arterial blood pressure measurement in 85 subjects and showed high accuracy 2.

CPP (Central Pulse Pressure)

Central Pulse Pressure by this monitor is estimated directly through pulse volume plethysmography (PVP) waveform analysis.

oscillometric central blood pressure monitor: a validation report for

Microlife WatchBP Office Central. Am J Hypertens, 2013. 26: 42-50.

24

MAP (Mean Arterial Pressure)The WatchBP Office Central device measures the true mean arterial pressure (MAP). Each measurement includes a single MAP value. The average measurement will display the average MAP value. When viewing in Memory mode, the MAP value will be displayed with the systolic and diastolic pressure once every 5 seconds.

PP (Pulse Pressure)This measurement device provides the pulse pressure (PP) of the patient: pulse pressure = systolic - diastolic pressure. Each measurement includes the calculation of a single PP value. The average measurement will display the average PP value. When viewing in Memory mode, the PP value will be displayed with the systolic/diastolic pressure once every 5 seconds.

* The Mean Arterial Pressure (MAP) in this device is determined from the maximum peak of the oscillometric envelope curve.

Appearance of the atrial fibrillation indicator for early detection The WatchBP Office Central is designed to screen for asymptomatic atrial fibrillation during blood pressure measurements in the «SCREEN» Mode. If two out of three measurements in the «SCREEN» Mode detect atrial fibrillation, the Afib icon is displayed. This device is able to detect atrial fibrillation with high accuracy: a sensitivity of 97% and a specificity of 89%.

About Atrial Fibrillation (Afib) Afib is a common heart rhythm problem. It affects more than 2 million people in North America. It is more common in older age and it is found in 18% individuals aged 85 years and older. It is a common cause of major strokes. About 15% of all strokes are caused by Afib.

The elderly, or those with high blood pressure, diabetes or heart disease are more likely to get a stroke if they have Afib.

Afib can last from a few minutes, to days or weeks and even years. Afib can cause blood clots in the upper chambers of the heart (the atria). These clots can break off and flow to the brain causing a stroke.

The use of blood thinners, such as warfarin, can lower the risk of a stroke in patients with Afib.

A doctor can confirm the presence of Afib by using a 12-lead ECG. Sometimes Afib is present incidentally. Therefore, a doctor may not see it on regularly scheduled visits.

One method of detecting Afib is by mean of palpations. This method is not very reliable. Failure of detecting Afib may lead to the occurrence of a stroke in the end; whereas early detection followed by adequate treatment can reduce the chance of stroke by two-thirds.


EN27


ABI (Ankle Brachial Index)The systolic blood pressure values of a person’s arm and leg need to be measured In order to determine ABI (Ankle Brachial Index).

The ankle-brachial index (ABI) is then calculated using the quotient of the systolic pressure from the leg measurement and the systolic pressure from the arm measurement.

A low ankle-brachial index (ABI) is indicative of systemic vascular disease, and places a patient in the high-risk category.
